Convert scale between wargaming, diecast, trains, and slot cars

Dave Farquhar model railroading, Toy trains , , , ,

Borrowing materials and models from other hobbies can often be productive, and in the early stages of a hobby, often it’s a necessity due to a lack of products available. But it occurs to me that other hobbies borrow from model railroading more often than the other way around, and that means there are untapped resources available. To do that, you need a way to convert scale between wargaming, diecast, trains, and slot cars.

In that spirit, I present a chart of scales. Two neglected train scales, O and S, it turns out, can borrow heavily from elsewhere to make up somewhat for the greater selection of products available for HO and N scale. But this chart will, I hope, prove useful to other hobbyists as well.

Using PC ATX power supplies on a train layout

Using PC ATX power supplies on a train layout

PC power supplies are exceptionally cheap and plentiful these days. If you’ve noticed and wondered whether you can use PC ATX power supplies on a train layout, wonder no more. You can.

Thanks to the miracle of mass production, even the cheapest, nastiest PC power supply gives far more power output per dollar than any train transformer. So if the lights and accessories on your electric train layout can run on 12 volts DC, which is a fairly good bet, you can get a lot of wattage for very little money by repurposing an inexpensive ATX power supply, whether new or secondhand. And on a wattage-per-dollar basis, they’re about twice as cost-effective as outdoor lighting transformers, which are another popular option for hobbyists. If you need AC power and more than 12 volts, get a lighting transformer. Otherwise, you can go ATX.

All it takes to use these cost-effective ATX power supplies is a bit of rewiring.

How to tell if a Lionel tender has a whistle

Dave Farquhar Toy trains , , ,

One of the things Lionel did that set its electric trains apart from its competitors was integrating a whistle in the tender that was included with its steam locomotives. Because of the added play value and charm, the whistling tender is a sought-after feature, even in this era when electronic sounds are so inexpensive that even dollar store toys sometimes have them.

Here’s how to quickly tell if a Lionel tender has a whistle.

Easier application whitelisting in Windows with App Locker

Dave Farquhar security, Windows , , ,

Application whitelisting is the holy grail of security, but it’s always at the top of the list of things people should do but haven’t yet. The reason is because it breaks stuff and it’s almost as impossible to anticipate ahead of time what it’s going to break as it is to fix whatever breaks.

I know. I wanted to do application whitelisting way back in 1997 and failed miserably.

I found a good-enough approach recently, though.

How to add a generic printer in Windows 10

Sometimes you need to add a generic printer in Windows 10.

Windows 10 makes the setup of newer hardware pretty automatic, but if you have a legacy or specialized printer that has to be set up as a generic printer in Windows, the process isn’t intuitive. Here’s how to set it up.

Where the red wire goes in a light fixture

Where the red wire goes in a light fixture

A friend was replacing a light fixture in his bathroom and ran into something confusing–a red wire in the electrical box along with the usual black and white wires. And when he hooked up his new light fixture, he did what I would expect the majority of homeowners to do. He connected the white wire on the fixture to the white wires in the box, and the black wire on the fixture to the black wires in the box. And then his light switch wouldn’t work. The light stayed on all the time. He was on the right track when he asked what the red wire is for.

It turns out the red wire was the key to solving his light fixture problem.

How to connect a Commodore VIC-20 to a TV

Connecting old computers and consoles to not-as-old televisions is frequently a challenge. Sadly, the VIC-20, Commodore’s runaway bestseller from 1982, is no exception to that. Here’s how to connect a Commodore VIC-20 to a TV.

Unfortunately, there are fewer options for connecting a VIC than there are the slightly newer and more common C-64, but I’ll walk you through the options you do have.

Here’s a better laptop than the typical Black Friday specials

Dave Farquhar Hardware, Saving money , , ,

If you want a better laptop than the typical Black Friday special, I found just the thing: this Dell Latitude E6420 laptop from Newegg, for $225 (the price is good through Sunday, Nov. 22). It has several things going for it: it comes with Windows 7 Professional, so you can upgrade to Windows 10 when you want and you’ll get the better, more-feature-filled, easier-to-secure Professional version; you can upgrade the memory to 8 GB of RAM, and it comes with a 128GB SATA SSD, so you can drop in a bigger, faster SSD at a later date.

Note: When Newegg sells out of these, which happens occasionally, they’re fairly easy to find on Ebay, though some come with conventional hard drives rather than SSDs.

A common question is whether Marx trains will work with Lionel crossovers, or vice versa. The answer is not well, but with a caveat. A big caveat. Here’s what to look out for with Lionel crossovers and Marx trains.
